yeah I heard they were dropping Chevy motors in them back when I had mine. BUt it goes so much farther than that.
Mine was the last year before they sold to Ford. not even counting end of the line creativity with parts, it has this incredibly elegant hydrolic system that controlled the suspension, breaks and power steering. It would literally on its own raise the body of the car on the low side of a turn and similarly lower the outsied to level the passenger experience. trouble was that the constant jiggling of the metal tubes running all over the car created leaks.
they simply were never able to be everyday cars.
